Description
Technical field
The utility model relates to a kind of noise monitoring system, especially a kind of bullet train noise wireless monitor system.
Background technology
The develop rapidly of high-speed railway allows the travelling speed of train constantly improve, but meanwhile, has also brought the increase of noise pollution during the speed-raising of train, and therefore in the factors of high-speed railway to environmental impact, noise becomes one of its principal element.So in the railway speed increase high speed, problem of noise pollution has become one of important topic that needs to be resolved hurrily and study.
Railway mainly is divided into external noise and internal noise, railway periphery resident's living environment can be polluted because of external noise: internal noise can directly have influence on the comfort level that the passenger takes train, particularly very fast when train running speed or when entering dangerous road, produce thus larger noise and will cause the physiology of passenger uncomfortable.Along with the renewal with life idea of improving constantly of people's living standard, people also continue to increase the attention degree of living environment, and noise pollution has become unavoidable environmental problem.
Noise intensity for clear and definite train, and the distribution of the source of noise and noise etc., need to be to each key position of train, comprise the noise testing that the guest room in the car, the pilothouse of train etc. are correlated with, therefore, the test of train noise also provides foundation for the design of optimizing motor train unit to the clear and definite important in inhibiting of noise source, distribution and the sound relation of shaking.
